Partial-year continuous light treatment reduces precocious maturation in age 1+ hatchery–reared male spring Chinook Salmon (Oncorhynchus tshawytscha)

Autor: Nick F Hoffman, Lea R Medeiros, Neil D Graham, Hayley M Nuetzel, Andrew L Pierce, James J Nagler

Publikováno v: Conservation Physiology. 11

Hatchery programs designed to conserve and increase the abundance of natural populations of spring Chinook Salmon Oncorhynchus tshawytscha have reported high proportions of males precociously maturing at age 2, called minijacks. High proportions of m

Feeding after spawning and energy balance at spawning are associated with repeat spawning interval in steelhead trout

Autor: Laura E. Jenkins, Lea R. Medeiros, Neil D. Graham, Brian M. Hoffman, Diana L. Cervantes, Douglas R. Hatch, James J. Nagler, Andrew L. Pierce

Publikováno v: General and comparative endocrinology. 332

Consecutive and skip repeat spawning (1- or ≥2-year spawning interval) life histories commonly occur in seasonally breeding iteroparous fishes. Spawning interval variation is driven by energetic status and impacts fisheries management. In salmonids

Plasma insulin-like growth factor-1 is unrelated to female reproductive development in a wild population of Dolly Varden charr Salvelinus malma (Walbaum, 1792)

Autor: James J. Nagler, Lea R. Medeiros, Andrew L. Pierce, Peter D. Bangs

Publikováno v: Hydrobiologia. 840:137-141

Insulin-like growth factors (IGFs) are endocrine agents that signal growth in fishes. Because of the interplay between growth and reproduction, endocrine control of the growth axis is thought to have a connection to the reproductive axis. Seasonal pa

Plasma nesfatin-1 is not affected by long-term food restriction and does not predict rematuration among iteroparous female rainbow trout (Oncorhynchus mykiss).

Autor: Lucius K Caldwell, Andrew L Pierce, Larry G Riley, Christine A Duncan, James J Nagler

Publikováno v: PLoS ONE, Vol 9, Iss 1, p e85700 (2014)

The metabolic peptide hormone nesfatin-1 has been linked to the reproductive axis in fishes. The purpose of this study was to determine how energy availability after spawning affects plasma levels of nesfatin-1, the metabolic peptide hormone ghrelin,

Reproductive development in captive reconditioned female steelhead kelts: evidence for consecutive and skip spawning life histories

Autor: Timothy D. Cavileer, Josh Boyce, Lea R. Medeiros, William J. Bosch, Andrew L. Pierce, David E. Fast, Joseph W. Blodgett, Douglas R. Hatch, Lucius K. Caldwell, James J. Nagler, Ryan Branstetter

Publikováno v: Canadian Journal of Fisheries and Aquatic Sciences. 74:1049-1060

Reconditioning of post-spawned anadromous rainbow trout (steelhead kelts, Oncorhynchus mykiss) is being implemented as a recovery tool on the Yakima River in the mid-Columbia River Basin. We assessed reproductive development in female Yakima River ke
